About This Product

The cathode ray tube is a key topic in school physics and electronics. A beam of electrons travels through a vacuum and lights up a phosphorescent surface where it strikes, and the beam can be steered by electric or magnetic fields. This explains how older television sets and computer monitors formed pictures, and it leads to the study of the oscilloscope and to the properties of electrons. Students should handle a vacuum tube with care because the glass is fragile.
